So when something does appear to change it’s worth taking note of. I have a feeling that a split may be developing on the ‘warmist’ side, between what we might call the ‘extremists’ and the ‘moderates’. Here are three recent examples of this.

Consensus?

Some social scientists believe that telling people that there’s a consensus on climate change acts as a ‘gateway belief‘ leading to public action, even though their own data does not really support this claim. Others have questioned this, saying that consensus messaging is an unhelpful distraction, see Geoff’s recent post and also this paper that says that other factors such as scientific integrity are more important.

Uninhabitable Earth?

One of the most ridiculous recent alarmist articles was The Uninhabitable Earth, by a journalist for New Yorker magazine, full of doom, terror, alarm, starvation and plagues. Because of this, it got a lot of attention, which presumably was the intention, and it even has its own wikipedia page. While David Roberts at Vox said that trying to scare people in this way was fine, many mainstream climate scientists criticised the article. A team at Climate Feedback (usually used to attack sceptical articles in the media) said that its scientific credibility was low and it exaggerated the risks. New Scientist said that such doomsday scenarios were unlikely to happen, and even Michael Mann thought that the article overstated the evidence.

Gore’s sequel?

Al Gore has a new film out, called “An Inconvenient Sequel”. He’s currently in the UK promoting it, which started the recent Lawson kerfuffle. Apparently his film has been an inconvenient flop at the box office. It’s no surprise that Bjorn Lomborg in the Wall Street Journal says that the film misses a few inconvenient facts. But what is more inconvenient for Mr Gore is that the Guardian doesn’t like it either, describing it as “desultory and surprisingly vainglorious” and awarding it only two stars. Apparently it is “more a portrait of Gore than a call to arms”.
